Also called a unit crest, the Distinctive Unit Insignia worn by personnel in the U.S. Army Element, Fort Belvoir Community Hospital was originally approved for DeWitt Army Hospital on 1 August 1969. It was redesignated on 22 August 1973 for the U.S. Army Medical Department Activity, Fort Belvoir and retained this designation for nearly forty years. The insignia was given its current designation, along with an updated description and symbolism, with an effective date of 18 July 2011.
The insignia consist of an inner Greek cross quartered with maroon and white—branch colors for Army Medicine—surmounted by a gold Greek cross containing three sets of narrow scarlet bars. At the insignia’s four corners are green oak leaves bearing a golden acorn, an allusion to new life and strength and the many years of service that Brigadier General Wallace DeWitt, MC, USA devoted to the medical service and the man after whom the facility was named.
Three sets of scarlet bars on a field of gold were suggested by the Coat of Arms of Thomas Lord Fairfax, acknowledging that Fort Belvoir was part of the original Fairfax land grant that comprised some 5.2 million acres. “Dedicated To Service,” the Hospital’s motto, is also a reference to General DeWitt’s lifelong mission.
Also known as a unit crest or DUI, the Distinctive Unit Insignia is worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (Enlisted only) with the base of the insignia toward the outside shoulder seam.
Full guidance on wear of the DUI is found in DA Pamphlet 670-1,
Section 21-22, "Distinctive unit insignia."
